This invention relates, generally, to iin provements in rubber toys for children; and

the nvention has reference,*n1ore particularly, to thattype of rubber toy which comprises a compressible hollow ,body provid-f ing; an interior air chamber which is fur-.

ther, provided, in the wall surrounding the same, v with 'an aperture with which 1s assoclated a sound em ssion means or whistle adapted to be operated when the hollow body is compressed to force the air from the interior chamber through said sound emission means.

Heretofore, it has been the practice,'in manufacture of toys of the character above described, to place within the aperture, leading -f1'onithe interior air chamber of the toy,

a metallic whistle element, usually possess-l ing front and rear annular marginal flanges between which themarginal portions-of the wall ofthe toy surrounding the aperture It has frequently been found, however, that Y were entered, thus holdthe whistle in place;

*the aperture by the child, and then the childs natural proclivities, especially the case of very small children, induce it to place the metallic whistle element in its mouth,

' with the disastrous result that the same is emitting device likely to slip down into the childs throat and lodging there induceschokingand quite;

frequently suffocation. It is the object of this invention to provide a toy of the kind described in which such easily displaced and therefore dangerous metallic sound emitting devices or whistles are eliminated, and a novel permanently built in and substantially integral, and therefore non-removable, sound. emitting device or whistle element is embodied in the structure of hollow rubber toys of the class here involved. p

The invention is clearly illustrated in the accompanying drawings, in which :v

Figure 1 is a rear elevation of a hollow rubber toy provided with the novel sound or whistle, made according to and embodying the principles of this invention; Figure 2 is a side elevation of the same, a portion of the hollow body of the toy being, ""broken -away v to ,show the novel PATENr sound emittingdevice or whistle in vertical,

section and: Figure 3v is a transverse vertical section, taken on line 3--3 111 said Figure 2.-

, Similar characters of reference'aree'mp loyed in all of the hereinab'ove described views, to indicate correspondmg parts.

Referring now tosaid drawings, the refer ence Character :1, indicates airubber ,toy, which may be molded in any desired fanciful form likely to be attactive'to children.

The ,toy'thus provided is-hollow to provide.

an interior air chamber 2. The material out of which the toy body is'made'being comparativelysoft-rubbenthe walls are yieldable or compressible, so that by squeezing or pinching the toy, the air in'the' chamber 2 may be compressed to actuate the novel sound emltting device or whistle with which I the toy is provided. The saidnovel sound emitting device or whistle is constructed in connection with a-suitable portion 3 of the mainwall of the toy, in which portion 3 of said main wall is provided with an aperture or opening 4:. Connectedwith the said mainwall 3, preferably soas to join the innner sidethereof, is a secondary wall or partition member 5, preferably of concavo convex form, whereby its marginalportions will join withthe main wall3 so as tosurround said aperture '01-, opening 1. Said united with the main wall 3 where it joins or abuts the latter. Said secondary wall or partition member' 5 is provided with an aperture or opening 6 whichis opposed to or alined with the aperture or opening 4 of the '85 secondary wall or partition member 5 is also made of rubber so as to be permanently main wall 8. It will be understood that the above described arrangement'of secondary.

wall or partition member 5, will thus have its central portion spaced somewhataway from the main wall 3, to thus provide intermediate the two, and thus intermediate the opposed apertures or openings l and 6 a whistle chamber 7. t It, is also preferable,

but. not absolutely essential, that the portion of said main wall 3 extending between the juncture of the secondary wall or partition member 5 therewith and the aperture or opening 4 be thickened toward the. latter, as shown at 8 in Figure 2; the advantage of such construction being that it obviates the tendency of the portion of the main wall' firmly. connected in operative assembled re-' bounding the whistlechamber 7 to collapse inwardly, whereby the latter chamber might be unduly diminished The operation of'fthe' novel structure above described is as follows l/Vhen the wallsof the toy are squeezed or pinched so as to compress the same, the

air in the chamber 2 will be driven outwardly therefrom to pass through the aperture or opening 6 into the whistle chamber 7 and thence escape through the aperture ingpre'ssure is relaxed, the natural resiliency of the rubber walls ofthe toy causes the latter to return to normal expanded condition, whereby air is sucked'through the aperture oropening a, whistle chamber 7, and aperture or opening 6 back into the interior air chamber 2 of the toy body, thus again causing. a sounding of the whistle structure.

"From' the above description of my invention, it will be quite evident that the whistle element is built into the toy as a fixed and non-removable part thereof, and consequently'entails none of'the dangers above referred to which are attendant upon the use of separate metallic whistle structures inlation to thetoy. As a consequence, my novel construction not only produces a toy safe for'babies and small children to possess, but also a toy which is indestructible as to its whistling function in the hands of such small children.

Some changes as to location and arrangement of the parts making up the novel feawall to provide an intermediate whistle chamber, said secondary wall having a 'cen tral aperture affording GODllllUIllCltlOIibB- tween said air chamber andfisaid whistle chamber, sald'main wall having an aperture.

affording communication between said whistle chamber and the atmosphere, the

substantially semi-spherical arch "of said concave-convex secondary wall being adapt ed to support the same against collapse relative to said main wall when the toy is com pressed to force air outwardly through the whistle chamber, and said portion of the main wall intermediate its aperture and the juncture of said secondary wall being of increasing thickness toward said aperture to-prevent inward collapse of'saicl mainwall toward saidsecondary wall when the toy is expanded to draw air inwardly through the Whistle'chamber'.

In testimony, that I claim the invention set forth above I have hereunto set my hand this ltth day of June, 1923;
